Five-month-old babies usually sleep around 15-16 hours, the exact time needs to vary from person to person, but at least need to ensure that the baby sleeps more than 10 hours a day. Under normal circumstances, a five-month-old baby is able to sleep 2-3 times during the day, for about 2-3 hours each time, with further extended waking hours. If the baby drinks milk normally, has normal height and weight development, and is in good spirits, an occasional change in sleep time generally has little effect and need not be a cause for concern. If your baby sleeps too little, consider that it is caused by hunger or physical discomfort. Because the baby’s stomach capacity is small, so the number of times to eat more frequently can cause the phenomenon of reduced sleep, the case should be timely to feed the baby, after drinking milk and then sleep, can take the right side of the bed, which is conducive to the digestion and absorption of food. In case of abnormal crying, poor mental state and other uncomfortable symptoms, it is recommended to visit the pediatrician. Five-month-old babies should pay attention to ensure sufficient sleep and try to go to bed on time. If the sleep time is long, you can help change the position. Usually, you should feed in time and ensure sufficient milk intake.
